91.9 g
9.19 x 10-2g
919 g
0.919 g
none of these
d
e

Answer 1

The answer is

91.9 g

Step-by-step explanation:

The mass of a substance when given the density and volume can be found by using the formula

mass = Density × volume

From the question

volume of copper = 10.3 mL

density = 8.92 g/mL

The mass is

mass = 8.92 × 10.3 = 91.876

We have the final answer as

91.9 g
